Addition polymerisation takes place either by a free radical mechanism or ionic mechanism depending on the reagents used. Free radical polymerisation is catalyzed by _______________, which decompose to give free radicals?
Correct answer: A. Organic peroxides
- A. Organic peroxides
- B. Sulphuric acid
- C. Hydrofluoric acid
- D. None of these
Explanation
Organic peroxides such as benzoyl peroxide decompose readily to form free radicals, which initiate addition polymerisation. Acids may catalyse ionic polymerisation but do not supply the usual free-radical initiators.
